Change made: Lamps, reflectors and electrical equipment – 4.1.4 Headlamps – Compliance with requirements – Sentence changed from ‘Some motorcycles may be fitted with high intensity discharge (HID) headlamps. Existing halogen headlamp units should not be converted to be used with HID bulbs. If such a conversion has been done, you must fail the headlamp.’ to ‘Some motorcycles may be fitted with high intensity discharge (HID) or light emitting diode (LED) headlamps. Existing halogen headlamp units should not be converted to be used with HID or LED bulbs. If such a conversion has been done, you must fail the headlamp.
Looks like the halogen bulb manufacturers have been doing some lobbying! I wonder if it due to accidents being found to be caused by dazzling or something?
